Theoretical Study Of The Effects Of Magnetic Field Geometry On The High-Energy Emission Of Blazars
Manasvita Joshi, Alan P. Marscher, Markus Boettcher
The knowledge of the structure of the magnetic field inside a blazar jet, as deduced from polarization observations at radio to optical wavelengths, is closely related to the forma…
X-rays from the location of the Bactrian Transient ASASSN-15lh
R. Margutti, B. D. Metzger, R. Chornock +13
We present the detection of persistent soft X-ray radiation with L_x ~ 10^41-10^42 erg/s at the location of the extremely luminous, double-humped transient ASASSN-15lh as revealed…
The GALEX Time Domain Survey. II. Wavelength-Dependent Variability of Active Galactic Nuclei in the Pan-STARRS1 Medium Deep Survey
T. Hung, S. Gezari, D. O. Jones +12
We analyze the wavelength-dependent variability of a sample of spectroscopically confirmed active galactic nuclei (AGN) selected from near-UV () variable sources in the GALEX…
Superluminous supernova 2015bn in the nebular phase: evidence for the engine-powered explosion of a stripped massive star
M. Nicholl, E. Berger, R. Margutti +25
We present nebular-phase imaging and spectroscopy for the hydrogen-poor superluminous supernova SN 2015bn, at redshift z=0.1136, spanning +250-400 d after maximum light. The light…
Gravitational Light Bending Prevents Absorption in Gravitational Lenses
Markus Boettcher, Hannes Thiersen
The magnification effect due to gravitational lensing enhances the chances of detecting moderate-redshift () sources in very-high-energy (VHE; GeV) -rays by…
Revisiting the Lick Observatory Supernova Search Volume-Limited Sample: Updated Classifications and Revised Stripped-Envelope Supernova Fractions
Isaac Shivvers, Maryam Modjaz, Weikang Zheng +11
We re-examine the classifications of supernovae (SNe) presented in the Lick Observatory Supernova Search (LOSS) volume-limited sample with a focus on the stripped-envelope SNe. The…
The Afterglow and Early-Type Host Galaxy of the Short GRB 150101B at z=0.1343
Wen-fai Fong, Raffaella Margutti, Ryan Chornock +14
We present the discovery of the X-ray and optical afterglows of the short-duration GRB 150101B, pinpointing the event to an early-type host galaxy at z=0.1343 +/- 0.0030. This make…
Discovery of Very High Energy Gamma Rays from 1ES 1440+122
VERITAS Collaboration, S. Archambault, A. Archer +87
The BL Lacertae object 1ES 1440+122 was observed in the energy range from 85 GeV to 30 TeV by the VERITAS array of imaging atmospheric Cherenkov telescopes. The observations, taken…
Radiation and Polarization Signatures of 3D Multi-zone Time-dependent Hadronic Blazar Model
Haocheng Zhang, Chris Diltz, Markus Böttcher
We present a newly developed time-dependent three-dimensional multi-zone hadronic blazar emission model. By coupling a Fokker-Planck based lepto-hadronic particle evolution code 3D…
A DECam Search for an Optical Counterpart to the LIGO Gravitational Wave Event GW151226
P. S. Cowperthwaite, E. Berger, M. Soares-Santos +97
We report the results of a Dark Energy Camera (DECam) optical follow-up of the gravitational wave (GW) event GW151226, discovered by the Advanced LIGO detectors. Our observations c…
PS1-14bj: A Hydrogen-Poor Superluminous Supernova With a Long Rise and Slow Decay
R. Lunnan, R. Chornock, E. Berger +27
We present photometry and spectroscopy of PS1-14bj, a hydrogen-poor superluminous supernova (SLSN) at redshift discovered in the last months of the Pan-STARRS1 Medium De…
Supplement: Localization and broadband follow-up of the gravitational-wave transient GW150914
B. P. Abbott, R. Abbott, T. D. Abbott +1538
This Supplement provides supporting material for arXiv:1602.08492 . We briefly summarize past electromagnetic (EM) follow-up efforts as well as the organization and policy of the c…
Collision-induced magnetic reconnection and a unified interpretation of polarization properties of GRBs and blazars
Wei Deng, Haocheng Zhang, Bing Zhang +1
The jet composition and energy dissipation mechanism of Gamma-ray bursts (GRBs) and Blazars are fundamental questions which remain not fully understood. One plausible model is to i…

Markus Boettcher, Paul Els
The expected level of gamma-gamma absorption in the Broad Line Region (BLR) radiation field of gamma-ray loud Flat Spectrum Radio Quasars (FSRQs)is evaluated as a function of the l…
Particle diffusion and localized acceleration in inhomogeneous AGN jets - Part II: stochastic variation
Xuhui Chen, Martin Pohl, Markus Böttcher +1
We study the stochastic variation of blazar emission under a 2-D spatially resolved leptonic jet model we previously developed. Random events of particle acceleration and injection…
